When you need to set the attribute of the IP address assignment of the APN, run the address-allocate command. Before running this command, run the apn
command to enter the APN view.

You can modify the
configuration successfully when users are available in the APN instance.

When access-mode is set to transparent-non-authentication, the IP addresses
cannot be assigned by the RADIUS server.

You can display the configuration information by running the display apn
command
